Abstract
Parameters are estimated for Bailey-Norton’s creep law and for a simplified ORNL plasticity model on the basis of Gauss-Newton’s and complex methods. Creep and plastic strains as given by the calibrated models are compared with experimental data and good agreement is found (particularly for creep strains). Finally, a numerical analysis has been carried out by considering a simple system subject to plastic and creep strains. The relevant results are reported and show satisfactory agreement with experimental data.
